QwtPlot->axisScaleDiv does not update after detaching curve

[Uwe]

As soon as you use a zoomer autoscaling gets turned off ( you are controlling the scales manually then - see QwtPlot::setAxisScale() ). Once autoscaling is off, there is no reason for updating the scales, when detaching a curve.
So you need to re-enable autoscaling manually, when you don't want the zoomer being in control anymore.

HTH,

Yes, that fixed this particular problem. Unfortunately I still have one connected to zoomer.

I have one thread being used exclusively for picking samples. Currently it has two modes - normal and "from zoomer". Normal mode is set to take samples from 0 to end (we display them for the first time), then it activates the slot in class inheriting QwtPlot, sets samples for curves and attaches curves to it. It works fine. But when it comes to zoomer weird things are happening. When is actually zoomer's "rescale" method called? I have feeling that it's called more often than only when I use zoomer to zoom or unzoom area.

What is more important - how can I reset zoom stack without multiple zoom -1 requests?
